CVE-2023-31094Network attack vector

Browser script execution via reflected page parameter

Published Aug 18, 2023 · Updated Apr 28, 2026

Reflected XSS in WP Trio Stock Sync for WooCommerce 2.4.0 and earlier allows remote attackers to run scripts via the page parameter. The plugin renders the attacker-controlled page parameter into an administrative page without sufficient input sanitization or output escaping. Execution requires a user to follow a crafted link, after which the script runs in that user's browser context and can read or alter data exposed to that session.
